"I have found a needle in a haystack the other day, someone who is dual qualified as a lawyer for English law and Dutch law."
Congratulations on finding that person. Now for the next question: Is that person competent? And how can you judge his competence in Dutch law? Can you read Dutch? How about Dutch legalese?
And good luck finding that chap with the Portugese qualifications, for whom similar questions apply.
